[0018] The following describes the embodiments and appendices. Figures 1 to 3 The technical solution of this utility model will be further described below.

[0019] Example 1

[0020] A welding device for medical pressure sensor chips includes: a workbench 1, a welding host 2, a chip base 3, a welding head assembly, a welding wire feeding assembly 5, and a chip blowing assembly 6. The welding host 2 is located on the right side of the workbench 1, and the chip base 3 is fixed on the left side of the workbench 1. The chip base 3 has a chip slot 34. The welding head assembly includes a welding head 41 and a drive assembly 42. The welding head 41 is raised and lowered by the drive assembly 42. The welding wire feeding assembly 5 feeds the welding wire between the welding head 41 and the chip base 3. The chip blowing assembly 6 includes a blower 61, a chip blowing pipe 62, a chip suction pipe 63, and an exhaust fan 64. The blower 61 and the exhaust fan 64 are located on the left side of the welding host 2. One end of the chip blowing pipe 62 is connected to the blower 61, and the other end of the chip blowing pipe 62 is positioned directly opposite the highest point on the front side of the welding head 41. One end of the chip suction pipe 63 is connected to the exhaust fan 64, and the other end of the chip suction pipe 63 is located behind the welding head 41.

[0021] like Figures 1 to 3 As shown, the working principle of this utility model is as follows: The workbench provides a support platform for the entire device, and the welding host, as the core control component, is responsible for providing the energy required for welding. The chip base is used to fix the chip, facilitating subsequent welding operations. The welding head assembly raises and lowers the welding head through the drive assembly, thereby welding the chip. The welding wire feeding assembly accurately feeds the welding wire between the welding head and the chip base, providing material for welding. The chip blowing assembly uses a blower and a chip blowing pipe to blow gas towards the front of the welding head, blowing excess solder from the welding head into the chip suction pipe, while the exhaust fan sucks away the blown solder debris through the chip suction pipe.

[0022] Highly efficient and stable welding is achieved through the coordinated work of various components. Compared to manual welding, the automated collaboration of these components significantly improves welding efficiency. Furthermore, the chip is fixed to the chip substrate, ensuring accurate welding positioning and improving welding quality. The chip removal component effectively solves the problem of solder residue, ensuring the quality of the chip surface.

[0023] As a further preferred embodiment, the drive assembly 42 includes a fixed base 421, a cylinder 422, a connecting rod 423, a clamp 424, a guide rail 425, and a slider 426. The fixed base 421 is fixed on the workbench 1 and located on the left side of the welding host 2. The cylinder 422 is disposed at the upper end of the fixed base 421, and the piston rod of the cylinder 422 is connected to the upper end of the connecting rod 423. The guide rail 425 is fixed in the middle of the fixed base 421. The slider 426 is fixed in the middle of the connecting rod 423 and is slidably disposed on the guide rail 425. The clamp 424 is fixed at the lower end of the connecting rod 423. The welding head 41 is disposed inside the clamp 424 and fixed by bolts.

[0024] The mounting bracket in the drive assembly provides support and a fixing point for the entire assembly. Cylinder 1 acts as the power source; the extension and retraction of its piston rod drives the connecting rod to move up and down. The cooperation of the guide rail and slider ensures smoother and more precise movement of the connecting rod during up and down motion, guaranteeing the stability of the welding head's lifting and lowering. The clamp is used to fix the welding head, and the bolt connection facilitates the replacement of different types of welding heads.

[0025] As a further preferred embodiment, the welding wire feeding assembly 5 includes a second cylinder 51, a guide seat 52, an adjusting plate 53, a frame 54, a motor 55, a drive gear 56, and a driven gear 57. The second cylinder 51, the guide seat 52, and the frame 54 are fixed on the worktable 1. The left end of the adjusting plate 53 is connected to the output end of the second cylinder 51 and is slidably disposed in the guide seat 52. The adjusting plate 53 and the right side are provided with welding wire through holes 531. The motor 55 is disposed at the lower end of the frame 54 and the output end of the motor 55 is connected to the drive gear 56. The driven gear 57 is rotatably connected to the frame 54 through a rotating shaft. The motor 55 drives the drive gear to feed the welding wire located between the drive gear 56 and the driven gear 57 to the side close to the chip base 3.

[0026] When welding is required, cylinder two pushes the adjusting plate to slide downward in the guide seat, causing the welding wire passing through the welding wire hole in the adjusting plate to press down on the surface of the chip welding position. After the welding action is completed, the welding wire moves upward to facilitate the placement of the next chip into the chip base. During the downward movement of the welding wire, the motor drives the drive gear to rotate. The welding wire sandwiched between the drive gear and the driven gear is transported to the chip base side by the friction force generated by the rotation of the drive gear.

[0027] In a further preferred embodiment, the chip base 3 includes a vertical plate 31, a lead wire plate 32, and a connecting plate 33. The connecting plate 33 has an adjustment hole 331, and the worktable 1 is connected to the adjustment hole 331 by a countersunk bolt 332. The vertical plate 31 is fixed to the left side of the connecting plate 33, the chip slot 34 is located at the top of the vertical plate 31, and the lead wire plate 32 is fixed to the left side of the vertical plate 31. The lead wire plate 32 has lead wire slots 321 spaced apart. The adjustment hole on the connecting plate is connected to the worktable by the countersunk bolt, which allows the position of the chip base to be adjusted according to actual needs, or different chip bases to be replaced to accommodate the welding of different models of medical pressure sensor chips. The vertical plate supports the chip slot and the lead wire plate. The chip slot is used to place the chip, and the lead wire slots on the lead wire plate are used to place the lead wires of the chip.

[0028] As a further preferred embodiment, the bottom of the chip slot 34 is provided with a circular groove 341 to facilitate the removal of the chip after soldering; the adjustment holes 331 are symmetrically arranged in two sets to improve the stability of the chip base 3 installation.

[0029] As a further preferred embodiment, a lighting lamp 7 is provided on the left side of the workbench 1 to provide sufficient light for the welding area, enabling the operator to observe the welding parts and welding process more clearly, facilitating timely detection and adjustment of problems, and helping to improve the accuracy and quality of welding.
